l 20 V Y IMPROVED RAG-CUTTER The Schedule referred to in these Letters Patent and making part: of the same.

ToaZl/whom it may concern:

Be it known that I, J. W, BARBOUR, of` Winooski Falls, in the count-y of Chittenden, andiStat-'e of ,Vermont, have invented a new and improved Rag-Gutter; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skille'd in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

This invention relates to improvements in machines for cutting rags and other substances for paper-steak,`

the object of which is to provide certain improvements in the arrangement of the cutters, as hereinafter more fully specified. l

Figure 1 represents a transverse sectional elevation, taken on the line x x of iig. 2.

Figure 2 represent-s a longitudinal sectional elevation, taken on the line y y of tig. 1.

Similar letters of reference indicate corresponding arts.

p l employ a large metallic disk, A, for supporting the movable cutters B, which I arrange in dovetail grooves in one side thereof, in lines running from the periphery to apoint slightly inadvanceof the axis, in the di` rection of the rotation of the'said disk, whereby a shear-cut is effected with the ix'ed knife C, the edge of which is in a radial line, the cut commencing at the inner and working towards the outer end.

Below the iixed knife C, I arrange another xed knife, D, parallel therewith, but considerably below the centre of the disk, whereby another shear-cut is also eiected upon the part of the rags previously cut and carried4 down to the lower fixed knife by the rotating c'uttersbetween the disk and the beam El of the ma'- (hine. This out begins at the outer ends of the knives and works inward.

lhe fixed knives G and D are made adjustable to or from the rotating knives.

In order to bring the feed-rollers as near tothe cutting-edges ofthe knives as possible for the better feeding of the rags, I make the stock of the knife C so as to curve around the front and under the lower feedroller adjacenty thereto, and extend behind it, for attachment to its support D', to permit ready access for adjusting it.

I propose to employ t-wo sets of feed-rollers F, ar-

ranging the inner set to have greater speed than the ias speoiiied.

J. W BARBOUR.
